Fans gave Kordell Stewart plenty of grief, but Bill Cowher stuck with his quarterback through some tough times.

In a divorce petition filed Friday in Fulton County Superior Court in Atlanta, Stewart says his marriage to Porsha Williams is "irretrievably broken" and the two are separated.

The pair appears on Bravo's "The Real Housewives of Atlanta."

The filing says the two married on May 21, 2011, and have no children together.

Stewart asks the court to find there are no marital assets to divide. He says Williams is "an able-bodied person, earning income, and is capable of supporting herself." He asks that neither side be ordered to pay alimony.

Stewart was a sensation in Pittsburgh in the late 1990s and was nicknamed "Slash" for his versatility as quarterback, running back and wide receiver.
